APPARATUS FOR MAKING IPRIIVNTERS ROLLERS.

SPECIFICATION forming part of Letters Patent No. 413,843, dated October 29, 1889.

' Application filed m t 13,1889. Serial No. 303,106. (No model-l To all whom it may concern:

Be it known that I, LEANDER K. BINGHAM,

a citizen of the UnitedStates, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Apparatus for Making Printers Rollers ,and I do declare the following to be a full, clear, and exact description, of the invention, such as will enable others skilled in the art to which it apper- A tains to make and use the same, reference part of the apparatus.

being had to. the accompanying drawings, and

1 to the letters of reference marked thereon,

which form a part of this specification.

Figure, l is a section on line ac m, Fig. 2, of Fig. 2 is a bottom ,view with part broken away.

This invention relates to improvements in apparatus for making printers rollers, more particularly to the construction of the lower part of the apparatus.

The invention consists in the construction hereinafter set forth.

In the annexed drawings, the letterAindicates the cylin'der'having the rim a. This cylinder has the usual lower head B, provided with the rim 1), which bears against the rim a, the head being secured to the cylinder at the rim. The head B has the holes b and underneath at these holes the countersinks b from which there run to the outer'edge the channels 12 which may be bottomless, as

shown. \Vithin the countersinks are the glands 0', having the threads 0, and between these glands and the head are the packings c. These-glands protrude through the holes I) and receive the lower ends (1 of the'moldtubes D, the upper ends of which are to be dropped, and around it is the removable bottom E, having the surrounding rim c. This rim has nozzles 6', there being as many as there are channels 12 in the head B.

After the roller-stocks are inserted into the mold-tubes in the usual way the bottom E is put in place, being centered by the guide pins f, with a .nozzle c registering with a channel b In this position it is held by the clamps. To a nozzle is connected the composition-supply pipe, and composition under pressure fiows through the channel and up into the mold-tube. After a tube is filled the supply-pipe is-moved to another nozzle, the tubethere filled, and so on until all are filled. With such an apparatus one or more tubes can be filled, and various difierent kinds of compositions can be used with the same apparatus.

Thenozzles 6 maybe provided with a stopcock or other closing device.

In another application of even date herewith, Serial No. 303,104, I have shown and claimed an apparatus the lower head of which has bottomless channels, and around such head is a bottom having a nozzle.

Having thus described my invention,what I claim is- The combination of the cylinder, its moldtubes,- the lower head having the holes for the mold-tubes, and the channels running from the holes to the edge of the head, with the bottom provided with the nozzles, as set forth.

Intestimon y whereof I affix my signature in presence of two witnesses.
